A CONTROVERSIAL 'children's book' called Go The F**k To Sleep has made its author $10 million.

Writer Adam Mansbach garnered admirers and critics in roughly equal measure after penning the expletive-laden book written in response to failed attempts to get his two-year-old daughter to bed.

But he can afford to shrug off the attacks – Go The F**k to Sleep has spent 65 weeks on the Amazon Best Sellers list and has made Mansbach $10 million.

The book topped the chart for much of that time and is still at No 3.

Although designed like a children's book the 32-page tome contains a selection of four line stanzas, each of which ends with the line 'Please go the f*** to sleep.'

Film rights have already been sold and no less a figure than Samuel L Jackson voiced the audio book.

Mr Mansbach, 34, is a visiting professor of fiction at Rutgers University and has several published works to his name.

He said: “I've been really amazed and gratified by the response.

“Obviously, this has hit a nerve; I knew it was funny when I wrote it, and it seemed like a universal sentiment, but it's been crazy to watch it take off.

'Even better, people seem to get the spirit in which it's intended - that it's an honest take on parenting, and that sometimes honesty is a little profane, but that doesn't mean we're not good parents, or that we don't love our kids.”

But Go The F**k To Bed isn't the only kids book on Amazon that't no fairy story.

Mansbach's book shares a page with macabre-sounding tales Monsters Eat Whiny Children by Bruce Eric Kaplan, All My Friends Are Dead by Avery Monsen and I Hate Everything by Matthew DiBenedetti.
